Introduction to Vaex in Python
In the realm of data science, handling large datasets presents significant challenges in memory management and execution speed. Vaex is a Python library designed specifically to address these problems by providing lazy evaluation and out-of-core processing capabilities. Vaex excels at analyzing, manipulating, and visualizing big data by leveraging modern hardware like multi-core CPUs and SSDs. Unlike traditional libraries, Vaex uses memory-mapping and lazy evaluation to perform calculations only when necessary. Why Use Vaex? Vaex overcomes limitations found in libraries like Pandas through several key features ? Lazy Evaluation − Computations are performed only when needed ...
Read MoreHow to Create Spring Bean in 3 Different Ways?
Spring is a highly popular framework within the Java EE ecosystem. It is an open-source and lightweight framework that empowers Java developers to build reliable, scalable, and simplified business applications. The primary goal of this framework is to offer you a variety of tools for managing your business items. In contrast to conventional Java frameworks and APIs such as JSP, JDBC and Java Servlet, developing web applications is far simpler. In Spring, objects—primarily those controlled by the Spring IoC Container. It plays a significant role in the application. A Bean is nothing more than an object that a Spring Ioc ...
Read MoreHow to Create Custom Class in Java?
In Java, a class is a fundamental component of object-oriented programming. It serves as a blueprint or template for defining the structure and behavior of objects. A class contains both data, represented by fields or variables, and behaviors, represented by methods or functions, which manipulate that data. In Java, a custom class is a user-defined class that allows you to create objects with specific properties and behaviors tailored to your application's requirements. It serves as a blueprint or template for creating objects of that class type. Custom classes encapsulate related data and operations into a single entity, promoting code organization, ...
Read MoreHow to Create and Setup Spring Boot Project in Eclipse IDE?
The Spring Boot framework incorporates all of Spring's capabilities and features because it is built upon the basis of Spring. Developers are drawn to it because of its effective production-ready environment, which frees them up to focus on the logic of the application rather than on setup and configuration. Microservices-based applications that are suitable for deployment in a production environment may be created quickly thanks to Spring Boot. Some of the key features of Spring Boot are − Auto-configuration − Spring Boot's standout feature is its auto-configuration capability. It analyzes the project's classpath and automatically configures the necessary beans ...
Read MoreHow to Create and Modify Properties File Form Java?
Program in Text and XML Format? In Java, a project's properties file is made up of text-based key-value pairs that are commonly stored with the .properties extension. The key-value pair of contents are presented line by line, and they are often created using notepad, Wordpad, etc. Properties files serve as valuable repositories for storing critical and confidential data. In this article, we will explore the process of creating a properties file using a Java program. The Properties class in this (java.util.Properties) package offers multiple utility store methods that facilitate the storage of properties in either Text Format or XML ...
Read MoreHow to Create a Thread-Safe ConcurrentHashSet in Java?
In this article, we will see what are the possibilities available to create thread-safe HashSet instances and see what will be equivalent to ConcurrentHashMap for HashSet. We will also look at the benefits and drawbacks of each approach. Before JDK8 we are not able to create a Thread Safe ConcurrentHashMap because java.util.concurrent package in JDK8 does not provide a class named ConcurrentHashSet, two new methods were added that are discussed below. ConcurrentHashMap is the Map implementation that allows us to modify the Map while iterating. The ConcurrentHashMap operations are thread-safe. ConcurrentHashMap doesn't allow null for keys and values. Ways to ...
